DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on preferred examples shown in the accompanying drawings;
[0015]
Example 1
FIG. 1 is an exploded perspective view illustrating a boiling pot having electric heating means according to a first embodiment of the present invention; and FIG. 2 is taken along line II of FIG. FIG. 3 is a cross-sectional view illustrating the assembled state of the boiling pot. 3 and 4 are partial enlarged cross-sectional views of a power supply portion, showing a position where power is supplied and a position where power is not supplied, respectively. FIG. 5 is a sectional view illustrating a state in which the boiling pot is in use.
[0016]
As shown in FIGS. 1 and 2, an exemplary cooking pot A has a pot body 10, a lid 20 built in at the top of the pot body 10, and a handle 22 formed on an upper surface of the lid 20. The auxiliary heating means 30 is formed inside the lid 20 and protrudes on the other side of the lid 20 relative to the pot body 10, and the vapor discharge means is formed on the side connected to the body of the lid. The means can control the steam release by the steam pressure in the cooking pot, equipped with a built-in power connection means 40, electrically connected to the heating coil and connected to an external power supply means 50. The feature is that it can be.
[0017]
Here, the auxiliary heating means 30 is formed as a coil portion 34 having a protruding portion facing the pot body 10 on the lid 20 and a conical cone-shaped profile on a pair of protruding electrodes. And furthermore, a heating panel 32 is formed outside the coil section 34, which covers the coil section and prevents contact with water and food.
The coil portion 34 of the auxiliary heating means 30 is formed on the other side of the lid, facing the pot body. More specifically, two flange means, each in the form of a pipe, are formed, one flange being fixed on the other side of the lid and the other flange being fixed on the heating plate 32 of the heating means 30, which is welded Alternatively, it is formed in one step by using a known coupling means such as a bolt.
[0018]
Further, the coil portion 34 of the auxiliary heating means 30 is electrically connected to a power supply connection means 40 formed at the upper end of the handle 22.
[0019]
A cylindrical side wall 24 is formed in an edge region of the lid 20. It couples with the periphery inside the pot body 10 to form the vapor discharge means of the cylindrical side 24. Any form of vapor release means is sufficient as long as it has an appearance that can be appropriately radiated. In this example, a slit is formed along the length direction of the cylindrical side portion 24 (perpendicular to the direction of the outer peripheral edge), and the opening of the slit for discharging the above to the outside discharges more as the steam pressure becomes higher. As the vapor pressure decreases, the open area decreases due to its own weight.
[0020]
The electrical connection means 40 as shown in FIGS. 3 and 4 includes a socket 41 and a pressing portion 47 formed at the upper end of the handle 22. A socket 41 formed by a body part 42 connected to the bottom of the handle 22 and an open holder part 43, which has a smaller outer diameter at the upper end of the body part 42 than the body part, Fifty plugs 42 can be inserted.
Here, the appearance of the socket 41 is cylindrical or rectangular. However, in this example, a cylindrical shape was adopted for convenience of explanation.
[0021]
Since the diameter of the holder portion 43 is smaller than the main body portion 42, a step difference occurs in the connection area between the holder portion 43 and the main body portion 42, and the formed press portion 47 can move up and down, It is inserted outside the holder part 43 and the body part 42. Furthermore, a connection terminal is formed which is electrically connected to the coil portion 34 of the heating means 30 in the holder 43, and the connection terminal is connected to a connection terminal of the plug 52.
[0022]
Pressing portion 47 includes a lower portion having a diameter greater than the outer diameter of body 42 of socket 41 and an upper portion having a diameter greater than the diameter of holder portion 43. Through holes are formed in the wall of the socket 41 and the holder portion 43 in opposite directions. A steel ball 45 is inserted into each of the through holes.
When the plug 52 is inserted into the socket 41, the steel ball is inserted into an engagement groove 53 formed in the plug 52. This has a role of maintaining the plug 52 and the socket 41 stably.
[0023]
Inside the upper part of the press part 47 (i.e. inside the connection with the holder part 43), arcuate grooves 48 having the same size as the steel balls 45 are formed facing each other. As will be described below, the arcuate groove 48 provides room for the rigid sphere to retract as the plug 53 is moved into and out of the holder portion 43 so that the inserted or ejected steel sphere 45 can be inserted. It is prevented from being released from the inside of the holder part 43.
[0024]
An engagement groove 53 having the same size as the steel ball 45 is formed on the outer surface of the plug 52, and the engagement groove 53, which coincides with the through hole 44 of the holder portion 43, allows the plug 52 to be completely inserted into the holder portion 43. When it is formed. When the plug 52 is inserted into the holder portion 43 of the socket 41, the steel ball 45 is inserted into the engagement groove 53, and the plug 52 and the socket 41 are stably combined.
[0025]
Also, as described above, a step difference occurs in the connection area between the main body portion 42 and the holder portion 43 of the socket 41, and this step difference is generated between the bottom portion and the upper portion of the pressing portion 47. Relative to the step difference in the connection area.
By opening the step portion formed on the pressing portion 47 and the socket 41 with the spring 49, the pressing portion is elastically supported along the length direction.
[0026]
Further, since the holder portion 43 of the socket 41 is opened upward, when the plug 52 is removed, the inflow of impurities such as steam and dirt is easy. Therefore, it is desirable to form a cover that can close an open face. The cover is located where it does not interfere with the insertion or removal, i.e. it is secured by a known hinge device on the outer periphery of the press part 47.
[0027]
The operation of the power supply connection element 40 will now be described with reference to FIGS. FIG. 3 shows a connection state of the plug 52 to the socket 41.

First, when connecting the plug 52 to the socket 41 by moving the pressing portion 47 downward by pressing it, when the steel ball 45 is located in the groove 48 of the press portion 47, the steel ball 45 can be retracted into the groove 48. it can. Therefore, the plug 52 inserted into the holder portion 43 of the socket 41 is not obstructed by the rigid sphere 45. When the plug 52 is completely connected to the holder part 43, the press part 47 is released. At this time, the press portion 47 is returned to the initial state. The plug 52 and the socket are as shown in FIG. 3 and maintain a stable connection.
[0029]
If the operation of pulling out the plug 52 from the holder 43 of the socket 41 is compared with the above connection, it has only one difference in the operation of insertion / separation, and the others are equal, so the detailed description is omitted. Description is omitted.
[0030]
The body 42 of the socket 41 may be formed with a plurality of drain holes 46 connected to the open bottom of the holder part 43 through the inside, and the drain holes 46 may condense steam generated during cooking. This is because of the drainage of water inside the holder part 43 due to At this time, the socket 41 and the plug 52 are insulated by a known method.
[0031]
